Hello Freesurfer team With your help i obtained a AAL atlas on the surface and 1 label for each region. However, when I load the label into the inflate image, I obtain something like the one submitted in this e-mail. I expected a solid ROI on the surface to obtain the volume, curvature, etc of the entire region. It's something wrong? I am loading the label in an incorrect way?
The image represent the label of the anterior cingulate into the inflated image
This might be the way it is given that the AAL is volume-based and you are trying to put it on the surface. What is your vol2surf command?

Hello, i used this code: mri_vol2surf --src /home/neuroimage/fsl/FreeSurfer/AAL.nii --regheader MNI --projfrac 0.5 --hemi lh --out /home/neuroimage/fsl/FreeSurfer/AAL-lh.mgh
Also i tried to map the AAL into the surface of fsaverage with: mri_vol2surf --mov /home/neuroimage/fsl/FreeSurfer/AAL.nii --reg /home/neuroimage/fsl/FreeSurfer/fsaverage_AAL/AAL_MNI2fsaverage.dat --projdist-max 0 1 0.1 --interp nearest --hemi rh --out rh_fsaverageAAL.mgh
The regions of the 2 methods are pretty similar but both have some holes into the ROIs
